Of course, the disagreement will not be tested in practice, because no one or very few will be willing to test his suggestion, seeing that such a test would be quite expensive.
Do you find my suggestion that such a test would be worth it for individual prospective donors to perform (based on expected returns considerations) unconvincing?
I have no doubt it would be worth it. In fact, I expect you are right. Even giving a beggar $20 instead of $1 increased my happiness significantly. But due to people’s selfishness, in general they will not be willing to test it even if the expected return is positive.
